Fixed on mainline.
Do we need this fixed for 4.0.1? If so, this will have to wait for the branch

Simplified testcase:
int *v;
int
*foo ()
{
extern int *v;
return static_castint * (v);
}
compiled with just -g on e.g. x86-64 or i386.

I have a GDB patch that will avoid the internal error. I'll dig it up.
I suppose there's room to argue that GCC's output is correct. Am I right in
thinking that the function-local extern could, in some

It is a regression since 3.4.x in the sense that the same testcase
was debuggable by gdb.
But the main question now is I think whether what g++ 4.0 emits is correct
or not.

As for whether the debug information is correct:
- It would be preferable if the full declaration was the one outside the

The testcase works if the variable declaration is moved after the function.
This is the case I fixed a few weeks ago, which was breaking java debugging.
The declare_in_namespace design causes us to get two
